A series testings and comparisons of material structure and chemical property of Richcel fiber are done to have worked out the processing route of Richcel/polyester blended spinning, and series tested the property of thus blended spun yarn.

In aqueous solutions, chemical property of cation or oxideacid anion of all same elements was great difference because difference valence condition.

Main causes of it are poor physical/chemical property and alkali aggregate reaction as there unexpectedly mixed with baked stone or re-active aggregate into the concrete batch.

A guiding coal to air ratio,formulated according to information signals,indicating the chemical energy contained in the fuel,fed into boiler furnace,and the heat released in the furnace,is then to be used during operation for realizing optimized control of the ratio.

This paper proposed the new concept of cascade utilization of chemical energy, which breakthrough the limitation of thermal energy conversion in the range of traditional thermal cycles, and theoretically proved the relationship of work availability between the material (exergy ε), the chemical reaction (Gibbs free energy G) and the thermal energy (Carnot efficiency ηc).

This paper anlyzed the process that chemical energy change into electrical ener- gy directiy according fo the thermodynamic theorem.

In order to provide theoretic basis for spinning,weaving,dyeing,finishing and so on process of decolour fleece\|line,we give the result compared to part of physical and chemical properties between the raw and bleaching camel fine hair.

To develop a new material with obstructive effects on bacteria,chemical properties of polypropylene(PP) hydroentangled nonwoven fabrics with three different mass per unit areas were investigated.

This paper outlines the principle and characteristics of the chemical energy storage and summarizes the thermophysical properties,advantages and disadvantages,and applications of seuerl kinds of typicsl chemical energy storage materials.
